DEVICE FOR TREATING TIMBER Filed July 29, 1947 Inventor Clinton .1. Gregory Attorneys Patented Feb. 22, 1949 UNITED STATES PATENT OFFICE DEVICE FOR TREATING TIMBER Clinton J. Gregory, Hot Springs, S. Dak. Application July 29, 1947, Serial No. 764,398

6 Claims. (01. 217) This invention relates to new and useful improvements in devices for treating timber and the primary object of the present invention is to provide a body that is partiallydriven into one end of a pile, post or the like and including novel and improved means for supplying fluid under pressure through the body to permeate the pores of the pile.

Another important object of the present inve tion is to provide a device'for treating timber including a hollow body, and a fluid receptacle for the body that is so positioned as to give a hydrostatic head to the fluid so that the same will enter the body in a convenient manner without the necessity of using a pump.

A further object of the present invention is to provide an apparatus for treating timber that is readily and quickly assembled for use or disassembled to facilitate convenient shipping or storing of the same.

A still further aim of the present invention is to provide a device for treating timber that is simple and practical in construction, strong and reliable in use, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which;

Figure 1 is a front elevational view of the present invention in use;

Figure 2 is a vertical sectional view taken substantially on the plane of section line 2-2 of Figure 1, and with parts of the fluid receptacle broken away and shown in section; and

Figure 3 is a top plan view of the present invention.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral l represents a hollow, preferably cylindrical body, closed at one terminal portion I2 and having its opposite terminal portion l4 annularly beveled or tapered facilitating the same to be driven into one end of a post, pile or the like l6.

Integrally formed with the body It adjacent the closed end thereof, is an internally threaded nipple l8 communicating with the interior of the body. This nipple receivably engages one externally threaded end of an inlet conduit 20. Threadingly engaging the opposite end of conduit20, is a T-joint 22, the free openings of which receivably engage branch pipes 24 and 26 extending outwardly from opposite sides of the joint 22. The axis of the branch pipes 24 and 26, is preferably disposed at right angles to the axis of the conduit 20.

The outer end of one of these branch pipes, for example, 24, is suitably coupled to the lower end of a vertically disposed tubular extension 28 communicating at its upper end with the lower portion of a fluid receptacle 3!). A manually operated valve 32 is interposed between the ends of the extension 28, for regulating a flow of fluid from the receptacle 30 to the conduit 20.

The outer end of branch pipe 26, is coupled by suitable means, to an air pressure line 34 leading from a suitable source of air pressure. A second manually operated valve 36 is interposed in branch pipe 26 for regulating the air pressure entering conduit 20.

It should be noted that the lower end of the fluid receptacle 30 is disposed in a horizontal plane above the closed end l2 of the body if], so that when Valve 32 is opened, fluid in the receptacle will flow under a hydrostatic head to the conduit 20 and by turning valve 36 in an open position, the fluid is forced through the pile IE to permeate the pores of the pile. Obviously, the fluid placed in the receptacle may be a solution of any desired character to preserve and add durable qualities to the pile.

During the driving operation of the tapered end Id of the body H] into the pile or the like 16, it is preferred that the conduit 20 be removed from the nipple [8, so that vibrations prevalent in the body during the driving, will in no way affect the tight connection of the conduit with the receptacle and the air pressure line.

In view of the foregoing description taken in conjunction with the accompanying drawing, it is believed that a clear understanding of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary,

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention, the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A device for treating timber comprising a hollow body closed at one end, the opposite end of said body being beveled to "engage one end of a pile, an inlet conduitfor said body, a fluid receptacle communicating with said conduit, means for regulating a flow of fluid from said receptacle to said conduit, an air pressure line connected to said conduit, and means for regulating pressure entering said conduit. 7

2. The combination of claim 1 wherein the 3.The-, combination of claim 1 wherein said means for regulating a flow of fluid from said receptacle to said conduit includes valve means. 4. A device for treating timber comprising a hollow body closed at one end, the opposite end" of said body being beveled, the beveled end. of

said body adapted to be driven into one end of lower end of said receptacle is disposed in a plane above the upper end of said body.

closed end, said nipple communicating with the interior oi said body, an inlet conduitreceivably engaging said nipple, a branch pipe carried by said conduit at right angles thereto, a vertical tubular extension at one end of said branch pipe,

. a fluid receptacle carried by said tubular extena pile, a nipple carried by saidbody adjacent it's closed end, said nipple communicating withthe interior of said body, an inlet conduit receivably engaging said nipple, and means for admitting fluid] under pressure into said conduit, said lastmentioned means including a branch pipe carried .by said conduit, said branch pipe being disposed at right angles to said'con'duit, a fiuidreceptacle connected to one end of said branchspipe, and.

an air pressure line connected to the other end of said branch pipe. 7 s

'5. The combination. of claim 4 wherein said fluid receptacle is disposed in a plane above the sion, a valve interposed in said extension for controlling a flow of fluid from said receptacle to said conduit, an air pressure line connected to the opposite end of said branch pipe, and a valve for regulating the air pressure entering said conduit.
